CFD Online Discussion Forums - Action Subtract or delete doesn't work in OpenFOAM

Hi Foamers,

I m doing chtMultiRegion for a heat transfer problem in a fin geometry. The geometry contains 4 regions including heated boundary, cold boundary , fin and air. I made a toposet to split the regions. However, it seems action delete doesnt work at the moment. Previously it was fine with the action delete since in my OpenFOAM version subtract action doesn't work. Now both subtract and delete actions are not working. Therefore, any tips that I can use to make this possible?

Here I attached the toposet dict file for your reference.
